Abstract: The advanced devices for Ultrawide Band (UWB), 5G, and Millimeter-wave communication demand an antenna that can handle massive data rates and provide high gain and better radiation patterns as a solution for most current wireless communication complications. Many different antennas have been designed. The Antipodal Vivaldi Antenna (AVA) has drawn the attention of most of the researchers because of its high gain, wider bandwidth, less radiation loss, and consistent radiation pattern. Different methods have been presented to enhance the performance of AVA. These different methods include varying the substrate material, radiating element’s flaring shape, slots, and feeding techniques. Further, AVA performance can be enhanced by incorporating corrugation, dielectric lens, patch in between two flares, balanced AVA (BAVA), metamaterial, and AVA array. Implementing enhancement techniques in AVA modifies the electrical and physical properties, which in turn improves its performance. This paper discusses a detailed review of Metamaterial-based Antipodal Vivaldi Antennas and a comparison of the antenna parameters.
